CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/579,457, filed Sep. 23, 2019, which is a continuation of U.S. patent application Ser. No. 15/820,789, filed Nov. 22, 2017, which is abandoned, which is a continuation of U.S. application Ser. No. 14/341,418, filed Jul. 25, 2014, issued as U.S. Pat. No. 9,867,117, which are hereby incorporated by reference in their entirety.

BACKGROUND

A network such as a local area network can comprise one or more network devices (e.g., access point (AP)) to provide a means for one or more user devices to communicate with and/or over the network. A network device can comprise a device that allows wired and/or wireless user devices to connect to a wired network using Wi-Fi, Bluetooth, or related standards. A network device can be configured to provide access to one or more services (e.g., private network, public network, network-related services). In certain Wi-Fi networks the AP can transmit a beacon. A user device can listen for this beacon to discover the AP availability in the local area. However, issues can arise when the user device discovers the presence of a WiFi network based on a perceived beacon strength, but the user device is unable to successfully connect and sustain a quality connection. For example, when the AP has a more powerful transmit power than the user device, this causes an asymmetric received signal strength indicator (RSSI) problem where the user device can receive and process the signal from the AP but the AP cannot receive and process the signal from the user device. Another problem is that the beacon is sent by the AP at the lowest configured rate at which the AP can transmit. Accordingly, improvements are needed for provisioning and managing devices connected to a network. These and other shortcomings are addressed by the present disclosure.

SUMMARY

It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive, as claimed. Methods and systems for managing network devices and providing services (e.g., network connectivity, broadband services, etc.) to one or more user devices or clients, are disclosed. The methods and systems described herein, in one aspect, can provide access to one or more services by one or more user devices or clients independent of the network to which the user devices are connected. In another aspect, the methods and systems described herein can dynamically configure a beacon transmission associated with a network device in order to selectively manage devices that are able to connect to the network device.

In an aspect, methods can comprise determining a first rate, for example, a first modulation rate and/or a first data transmission (e.g., transfer) rate, associated with a network device. A beacon can be transmitted at a second rate, for example, second modulation rate and/or a second data transmission (e.g., transfer) rate, wherein the second rate is greater than the first rate. A user device can be associated with the network device based on the beacon if the user device is configured to support the second rate.

In another aspect, methods can comprise determining a first transmit power associated with a network device. The first transmit power can relate to a data transfer rate supported by the network device. A beacon can be transmitted at a second transmit power. The second transmit power can be different, e.g., less, than the first transmit power. A user device can be associated with the network device based on the beacon if the user device is configured to receive the beacon.

In a further aspect, methods can comprise determining a first characteristic associated with a network device. The first characteristic can relate to one or more of a transmit power and a noise floor. A second characteristic associated with a user device can be determined. The second characteristic can relate to a received signal strength. An estimate of a quality of connectivity between the user device and the network device can be determined. The user device can be associated with the network device if the estimate of the quality of connectivity exceeds a threshold value.

Additional advantages will be set forth in part in the description which follows or may be learned by practice. The advantages will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive, as claimed.

In one aspect of the disclosure, a system can be configured to provide services such as network-related services. FIG. 1 illustrates various aspects of an exemplary environment in which the present methods and systems can operate. The present disclosure is relevant to systems and methods for providing services to a user device, for example. Those skilled in the art will appreciate that present methods may be used in various types of networks and systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware.

The network and system can comprise a user device 102 in communication with a computing device 104, such as a server, for example. The computing device 104 can be disposed locally or remotely relative to the user device 102. As an example, the user device 102 and the computing device 104 can be in communication via a private and/or public network 105, such as the Internet. Other forms of communications can be used, such as wired and wireless telecommunication channels, for example.

In an aspect, the user device 102 can be an electronic device, such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, or other device capable of communicating with the computing device 104. As an example, the user device 102 can comprise a communication element 106 for providing an interface to a user to interact with the user device 102 and/or the computing device 104. The communication element 106 can be any interface for presenting information to the user and receiving a user feedback, such as a application client or a web browser (e.g., Internet Explorer, Mozilla Firefox, Google Chrome, Safari, or the like). Other software, hardware, and/or interfaces can be used to provide communication between the user and one or more of the user device 102 and the computing device 104. As an example, the communication element 106 can request or query various files from a local source and/or a remote source. As a further example, the communication element 106 can transmit data to a local or remote device, such as the computing device 104.

In an aspect, the user device 102 can be associated with a user identifier or device identifier 108. As an example, the device identifier 108 can be any identifier, token, character, string, or the like, for differentiating one user or user device (e.g., user device 102) from another user or user device. In a further aspect, the device identifier 108 can identify a user or user device as belonging to a particular class of users or user devices. As a further example, the device identifier 108 can comprise information relating to the user device, such as a manufacturer, a model or type of device, a service provider associated with the user device 102, a state of the user device 102, a locator, and/or a label or classifier. Other information can be represented by the device identifier 108.

In an aspect, the device identifier 108 can comprise an address element 110 and a service element 112. In an aspect, the address element 110 can be an internet protocol address, a MAC address, a network address, an Internet address, or the like. As an example, the address element 110 can be relied upon to establish a communication session between the user device 102 and the computing device 104 or other devices and/or networks. As a further example, the address element 110 can be used as an identifier or locator of the user device 102. In an aspect, the address element 110 can be persistent for a particular network and/or location.

In an aspect, the service element 112 can comprise an identification of a service provider associated with the user device 102 and/or with the class of user device 102. As an example, the service element 112 can comprise information relating to or provided by a communication service provider (e.g., Internet service provider) that is providing or enabling communication services to the user device 102. As a further example, the service element 112 can comprise information relating to a preferred service provider for one or more particular services relating to the user device 102. In an aspect, the address element 110 can be used to identify or retrieve the service element 112, or vise versa. As a further example, one or more of the address element 110 and the service element 112 can be stored remotely from the user device 102 and retrieved by one or more devices, such as the user device 102 and the computing device 104. Other information can be represented by the service element 112.

In an aspect, the computing device 104 can be a server for communicating with the user device 102. As an example, the computing device 104 can communicate with the user device 102 for providing services. In an aspect, the computing device 104 can allow the user device 102 to interact with remote resources, such as data, devices, and files. As an example, the computing device can be configured as central location (e.g., a headend, or processing facility), which can receive content (e.g., data, input programming) from multiple sources. The computing device 104 can combine the content from the various sources and can distribute the content to user (e.g., subscriber) locations via a distribution system.

In an aspect, the computing device 104 can manage the communication between the user device 102 and a database 114 for sending and receiving data therebetween. As an example, the database 114 can store a plurality of data sets (e.g., mapped identifiers, relational tables, user device identifiers (e.g., identifier 108) or records, network device identifiers (e.g., identifier 118), or other information). As a further example, the user device 102 can request and/or retrieve a file from the database 114. In an aspect, the database 114 can store information relating to the user device 102, such as the address element 110 and/or the service element 112. As an example, the computing device 104 can obtain the device identifier 108 from the user device 102 and retrieve information from the database 114, such as the address element 110 and/or the service elements 112. As another example, the computing device 104 can obtain the address element 110 from the user device 102 and can retrieve the service element 112 from the database 114, or vice versa. As a further example, the computing device 104 can obtain a MAC address from the user device 102 and can retrieve a local IP address from the database 114. As such, the local IP address can be provisioned to the user device 102, for example, as the address element 110 to facilitate interaction between the user device 102 and a network (e.g., LAN). Any information can be stored in and retrieved from the database 114. The database 114 can be disposed remotely from the computing device 104 and accessed via direct or indirect connection. The database 114 can be integrated with the computing system 104 or some other device or system.

In an aspect, one or more network devices 116 can be in communication with a network, such as network 105. As an example, one or more of the network devices 116 can facilitate the connection of a device, such as user device 102, to the network 105. As a further example, one or more of the network devices 116 can be configured as a network gateway. In an aspect, one or more network devices 116 can be configured to allow one or more wireless devices to connect to a wired and/or wireless network using Wi-Fi, Bluetooth or similar standard.

In an aspect, the network devices 116 can be configured as a mesh network. As an example, one or more network devices 116 can comprise a dual band wireless network device. As an example, the network devices 116 can be configured with a first service set identifier (SSID) (e.g., associated with a user network or private network) to function as a local network for a particular user or users. As a further example, the network devices 116 can be configured with a second service set identifier (SSID) (e.g., associated with a public/community network or a hidden network) to function as a secondary network or redundant network for connected communication devices.

In an aspect, one or more network devices 116 can comprise an identifier 118. As an example, one or more identifiers can be a media access control address (MAC address). As a further example, one or more identifiers 118 can be a unique identifier for facilitating communications on the physical network segment. In an aspect, each of the network devices 116 can comprise a distinct identifier 118. As an example, the identifiers 118 can be associated with a physical location of the network devices 116.

In an aspect, the user device 102 can discover a beacon 120 transmitted (e.g., wirelessly) by the network device 116. The beacon 120 can comprise a beacon frame. As an example, the beacon frame can comprise information relating to the network. As a further example, the beacon frame can comprise a timestamp to synchronize two or more devices (network device 116), a beacon interval at which a node (network device 116) must send a beacon; and capability information. The beacon 120 can comprise information to facilitate a connection between the user device 102 and the network device 116. In another aspect, a broadcast rate (e.g., data transmission rate, modulation rate) of the network device 116 can be configured at a custom rate. As an example, the beacon 120 transmitted by the network device 116 can advertise the minimum acceptable rate (e.g., data transmission rate, modulation rate) that is required to connect to the network device 116. As such, if a user device 102 is in range of the beacon 120, but is not able to demodulate the beacon 120, the user device 102 is unable to discover the network device 116 and may not be able to connect to the network device. As another example, if the network device 116 can support the following rates (in Mbps): 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54, the beacon 120 can be transmitted at 18 Mbps in order to reduce the circumference in which the beacon could be de-modulated. This would allow the user device 102 to use lower rates than 18 Mbps, but to not discover the broadcast and attempt connection until the user device 102 was able to de-modulate 18 Mbps. As another example, if the network device 116 can support the following rates (in Mbps): 7.2, 14.4, 21.7, 28.9, 43.3, 57.8, 65, 72.2, the beacon 120 can be transmitted at 21.7 Mbps instead of 7.2 Mbps in order to reduce the circumference that the beacon could be de-modulated. As a further example, the network device 116 may be configured to support various rates, such as less than or equal to 87.6 Mbps, less than or equal to 200 Mbps, less than or equal to 433.3 Mbps, less than or equal to 866.7 Mpbs, less than or equal to 6912 Mbps, or other rates or ranges. In an aspect, any rate can be used, such as rates allowed by governing agencies such as the Federal Communications Commission (FCC) and the like.

In a further aspect, the user device 102 may be required to be within a particular range of the network device 116 in order to discover the beacon 120. In an aspect, the network device 116 can configure a transmit power specifically for the beacon 120. As an example, the beacon 120 can be transmitted at a first transmit power that is lower than a second transmit power used for the transmission of network data. As a further example, data can be transmitted at a power of 23 dBm and the beacon 120 can transmit at a power of 15 dBm. This would reduce the area that a user device 102 could discover the broadcast of the beacon 120, but would not affect the actual data service area of the network device 116 for all devices.

In an aspect, various characteristics can be communicated between the user device 102 and the network device 116 to evaluate link quality. As an example, an RSSI associated with the user device 102 can be received by the network device 116 and can be returned to the user device 102. The user device 102 can use the returned RSSI to determine the quality of uplink and downlink for the connection between the user device 102 and the network device 116. As an example, information relating to a transmit power and/or a noise floor of the network device 116 can be transmitted to one or more user devices 102. Using this information about the network device 116 and/or the RSSI measured by the user device 102, the device can calculate a path loss. Knowing this path loss, the noise floor at the network device 116, and the characteristics of a transmitter of the user device 102, the user device 102 can calculate a quality of connectivity, such as the probability that its uplink will be received by the network device 116.

In an aspect, path loss can be calculated based on the transmission power (P_(tx1)) and an RSSI associated with the network device 116. As an example, path loss can be calculated based on P_(tx1)−RSSI=L_(p) (path loss). In another aspect, a quality of connectivity (e.g., signal-to-noise ratio (SNR)) can be calculated based on the transmission power (P_(tx2)) associated with the user device 102, the L_(p), and the noise floor (N) associated with the user device 102 or the network device 116. As an example, SNR can be calculated (e.g., estimated) based on P_(tx2)(dBm)−L_(p)(dB)−N(dBm)=SNR(dB), wherein N can be associated with one or more of the user device 102 or the network device 116. Other functions and characteristics can be used to determine path loss and/or quality of connectivity.

In an exemplary aspect, the methods and systems can be implemented on a computing system, such as computing device 201 as illustrated in FIG. 2 and described below. By way of example, one or more of the user device 102 and the computing device 104 of FIG. 1 can be a computer as illustrated in FIG. 2 . Similarly, the methods and systems disclosed can utilize one or more computers to perform one or more functions in one or more locations.

Generally, program modules comprise computer code, routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The disclosed methods can also be practiced in grid-based and distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote computer storage media including memory storage devices.

Further, one skilled in the art will appreciate that the systems and methods disclosed herein can be implemented via a general-purpose computing device in the form of a computing device 201.

The computing device 201 typically comprises a variety of computer readable media. Exemplary readable media can be any available media that is accessible by the computing device 201 and comprises, for example and not meant to be limiting, both volatile and non-volatile media, removable and non-removable media. The system memory 212 comprises computer readable media in the form of volatile memory, such as random access memory (RAM), and/or non-volatile memory, such as read only memory (ROM). The system memory 212 typically contains data, such as network data 207, and/or program modules, such as operating system 205 and network software 206, that are immediately accessible to and/or are presently operated on by the processing unit 203.

In another aspect, the computing device 201 can also comprise other removable/non-removable, volatile/non-volatile computer storage media. By way of example, FIG. 2 illustrates a mass storage device 204 which can provide non-volatile storage of computer code, computer readable instructions, data structures, program modules, and other data for the computing device 201. For example and not meant to be limiting, a mass storage device 204 can be a hard disk, a removable magnetic disk, a removable optical disk, magnetic cassettes or other magnetic storage devices, flash memory cards, CD-ROM, digital versatile disks (DVD) or other optical storage, random access memories (RAM), read only memories (ROM), electrically erasable programmable read-only memory (EEPROM), solid state drives, and the like.

Optionally, any number of program modules can be stored on the mass storage device 204, including by way of example, an operating system 205 and network software 206. Each of the operating system 205 and network software 206 (or some combination thereof) can comprise elements of the programming and the network software 206. Network data 207 can also be stored on the mass storage device 204. Network data 207 can be stored in any of one or more databases known in the art. Examples of such databases comprise, DB2®, Microsoft® Access, Microsoft® SQL Server, Oracle®, mySQL, PostgreSQL, and the like. The databases can be centralized or distributed across multiple systems.

In another aspect, the user can enter commands and information into the computing device 201 via an input device (not shown). Examples of such input devices comprise, but are not limited to, a keyboard, pointing device (e.g., a “mouse”), a microphone, a joystick, a scanner, tactile input devices such as gloves, and other body coverings, and the like These and other input devices can be connected to the processing unit 203 via a human machine interface 202 that is coupled to the system bus 213, but can be connected by other interface and bus structures, such as a parallel port, game port, an IEEE 1394 Port (also known as a Firewire port), a serial port, or a universal serial bus (USB).

In yet another aspect, a display device 211 can also be connected to the system bus 213 via an interface, such as a display adapter 209. It is contemplated that the computing device 201 can have more than one display adapter 209 and the computer 201 can have more than one display device 211. For example, a display device can be a monitor, an LCD (Liquid Crystal Display), or a projector. In addition to the display device 211, other output peripheral devices can comprise components, such as speakers (not shown) and a printer (not shown) which can be connected to the computing device 201 via Input/Output Interface 210. Any step and/or result of the methods can be output in any form to an output device. Such output can be any form of visual representation, including, but not limited to, textual, graphical, animation, audio, tactile, and the like. The display 211 and computing device 201 can be part of one device, or separate devices.

The computing device 201 can operate in a networked environment using logical connections to one or more remote computing devices 214 a,b,c. By way of example, a remote computing device can be a personal computer, portable computer, a smart phone, a server, a router, a network computer, a peer device or other common network node, and so on. Logical connections between the computing device 201 and a remote computing device 214 a,b,c can be made via a network 215, such as a local area network (LAN) and a general wide area network (WAN). Such network connections can be through a network adapter 208. A network adapter 208 can be implemented in both wired and wireless environments. Such networking environments are conventional and commonplace in dwellings, offices, enterprise-wide computer networks, intranets, and the Internet.

For purposes of illustration, application programs and other executable program components, such as the operating system 205, are illustrated herein as discrete blocks, although it is recognized that such programs and components reside at various times in different storage components of the computing device 201, and are executed by the data processor(s) of the computer.

As an example, the computing device 310 can be or comprise an application server, management device, auto-configuration server (ACS), AAA server, etc. In another aspect, the computing device 310 is located within a network, such as a wide area network (WAN).

In an aspect, the user device 303 can discover a beacon 312 transmitted (e.g., wirelessly) by the node 302 b. The beacon 312 can comprise a beacon frame. The beacon 312 can comprise information to facilitate a connection between the user device 303 and the network device 116. In another aspect, a broadcast rate (e.g., data transmission rate, modulation rate) of the node 302 b can be configured at a custom rate. As an example, the beacon 312 transmitted by the node 302 b can advertise the minimum acceptable rate (e.g., data transmission rate, modulation rate) that is required connect to the node 302 b. As such, if a user device 303 is in range of the beacon 312, but is not able to demodulate the beacon 312, the user device 303 is unable to discover the node 302 b and may not be able to connect to the network device. As another example, if the node 302 b can support the following rates (in Mbps): 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54, the beacon 312 can be transmitted at 18 Mbps in order to reduce the circumference that the beacon could be de-modulated. This would allow the user device 303 to use lower rates than 18 Mbps, but to not discover the broadcast and attempt connection until the user device 303 was able to de-modulate 18 Mbps. As another example, if the node 302 b can support the following rates (in Mbps): 7.2, 14.4, 21.7, 28.9, 43.3, 57.8, 65, 72.2, the beacon 312 can be transmitted at 21.7 Mbps instead of 7.2 Mbps in order to reduce the circumference that the beacon could be de-modulated. As a further example, the node 302 b may be configured to support various rates, such as less than or equal to 87.6 Mbps, less than or equal to 200 Mbps, less than or equal to 433.3 Mbps, less than or equal to 866.7 Mpbs, less than or equal to 6912 Mbps, or other rates or ranges. In an aspect, any rate can be used, such as rates allowed by governing agencies such as the Federal Communications Commission (FCC) and the like.

In a further aspect, the user device 303 may be required to be within a particular range of the node 302 b in order to discover the beacon 312. In an aspect, the node 302 b configures a transmit power specifically for the beacon 312. As an example, the beacon 312 can be transmitted at a first transmit power that is lower than a second transmit power used for the transmission of network data. As a further example, data can be transmitted at a power of 23 dBm and the beacon 312 can transmit at a power of 15 dBm. This would reduce the area in which the user device 303 could discover the broadcast of the beacon 312, but would not affect the actual data service area of the node 302 b for all devices.

In an aspect, the node 302 b can be configured to transmit two or more beacon 312 at different transmit power levels or rates (e.g., data transmission rates, modulation rates). The configuration of the node 302 b can be based on capabilities of the node 302 b, capabilities of the user device 303, class of the user device 303, service plane, class of a user, etc. Two or more user device 303 can discovery the two or more beacons 312 and associated with (e.g., connect to) the network. Accordingly, a single network device (e.g., node 302 b) can provide beacons 312 for two or more user devices 303 having different capabilities. For example, a first user device 303 may discovery a beacon 312 having a rate of 18 Mbps and a second user device 303 can discovery a beacon 312 having a rate of 54 Mpbs.

In an aspect, an RSSI associated with the user device 303 can be received by the node 302 b and can be returned to the user device 303. The user device 303 could use the returned RSSI to determine the quality of uplink and link-down for downlink the connection between the user device 303 and the node 302 b. Other characteristics can be communicated between the user device 303 and the node 302 b. As an example, information relating to a transmit power and/or a noise floor of the node 302 b can be transmitted to one or more user devices 303. Using this information about the node 302 b and/or the RSSI measured by the user device 303, the device can calculate a path loss. Knowing this path loss, the noise floor at the node 302 b, and the characteristics of a transmitter of the user device 303, the user device 303 can calculate the probability that its uplink will be received by the node 302 b. As an example, an RSSI associated with the user device 303 can be received by the node 302 b and can be returned to the user device 303. The user device 303 could use the returned RSSI to determine the quality of uplink/downlink for the connection between the user device 303 and the node 302 b. As an example, information relating to a transmit power and/or a noise floor of the node 302 b can be transmitted to one or more user devices 303. Using this information about the node 302 b and/or the RSSI measured by the user device 303, the device can calculate a path loss. Knowing this path loss, the noise floor at the node 302 b, and the characteristics of a transmitter of the user device 303, the user device 303 can calculate the quality of connectivity, such as the probability that its uplink will be received by the node 302 b.

In an aspect, the path loss can be calculated based on the transmission power (P_(tx1)) and an RSSI associated with the node 302 b. As an example, the path loss can be calculated based on P_(tx1)−RSSI=L_(p) (path loss). In another aspect, a quality of connectivity (e.g., signal-to-noise ratio (SNR)) can be calculated based on transmission power (P_(tx2)) associated with the user device 303, the L_(p) and the noise floor (N) associated with the user device 303 or the node 302 b. As an example, SNR can be calculated (e.g., estimated) based on P_(tx2)(dBm)−L_(p)(dB)−N(dBm)=SNR(dB), wherein N can be associated with one or more of the user device 303 or the node 302 b. Other functions and characteristics can be used to determine path loss and/or quality of connectivity.

As shown in FIG. 4 , a first network 402 a can comprise one or more of the nodes 302 a, 302 b, 302 c, 302 d and/or the gateway 304 a and a second network 402 b can comprise one or more nodes (e.g., node 302 e) and/or a gateway 304 b. In an aspect, each of the first network 402 a and the second network 402 b can be associated with an identifier, such as an SSID.

In an aspect, a device such as the user device 303 can discover a beacon transmitted (e.g., wirelessly) by the node 302 e and can use the beacon to connect to node 302 e. However, user device 303 may not be able to discover the nodes 302 a, 302 b, 302 c, 302 d. As an example, the transmit power and/or the broadcast rate (e.g., data transmission rate, modulation rate) of the node 302 e can be such that the user device 303 can receive the beacon associated with node 302 e and demodulate the information contained in the beacon in order to connect to node 302 e. Although the user device 303 may be in range of the nodes 302 a, 302 b, 302 c, 302 d in order to process data (if connection was enabled), the user device 303 may not be able to discover the nodes 302 a, 302 b, 302 c, 302 d because of the configurations of the advertising (e.g., beacon) of the nodes 302 a, 302 b, 302 c, 302 d. As such, the nodes 302 a, 302 b, 302 c, 302 d can selectively manage the devices (e.g., user device 303) that can connect to the nodes 302 a, 302 b, 302 c, 302 d based on whether the devices are configured to process designated minimum requirements (e.g., modulation rate, demodulation rate, transmit power, RSSI, noise floor, SNR, etc.). The nodes 302 a, 302 b, 302 c, 302 d and node 302 e can be part of the same network, such as a LAN. Any of the nodes 302 a, 302 b, 302 c, 302 d, 302 e can have a configurable beacon for selectively managing admission to the network. For example, one or more of the nodes 302 a, 302 b, 302 c, 302 d, 302 e can be disposed in a congested area having multiple network devices. Accordingly, the one or more of the nodes 302 a, 302 b, 302 c, 302 d, 302 e can be configured to restrict admission to the network based upon any number of characteristics.

In a further aspect, the first transmit power can be equal to or less than the maximum transmit power allowed by the local regulation authority (e.g., +36DBM EIRP in the US as regulated by the FCC or the territorial equivalent) and/or supported by the network device.

In step 604, a beacon can be transmitted. In an aspect, the beacon can be transmitted at a second transmit power.
